Are we Alone in the Universe?

There are many theories that pretend to explain the possibility of finding life on other worlds in the universe. Some tell why our planet is not unique in a universe that is so immense and still expanding, with many stars being formed and earth-like planets forming around those stars. With the use of high technology and space probes crossing the solar system and beyond., our reach knowledge of the universe is minimum; however, the probabilities of life being produced distant planets is a possibility if the scenario is given for a planet to form near a star with a distance similar the distance of earth. Intelligent life on other planets is a possibility; that reduces the hopes of some who think that being part of the genus Homo sapiens on earth is synonym of being unique.

Life Forms Abound on Earth

Life abounds on earth. There are more human beings now than in the beginning of man´s history on earth. Our early ancestors, the apes began to exist around 5 million years ago and the early humans derived from apes with human-like behavior began to exist around 50.000 years ago. From there, humans began to proliferate and spread among many regions on earth, carrying with them other life forms in the form of bacteria and microbes, which is a kind of diminutive biological life which cannot be seen, unless one uses a microscope.

These are tiny single-celled life forms made of the same basic life form as humans and which according to one study man descends from. Since the beginning of life on planet earth, humans have not been alone, they have had the company of these tiny life forms and which form part of a whole in the human organism.

Life Found out of Earth

A new bacterium called Tersicoccus phoenicis was found in a room atop a platform at the European Space Agency in 2009 and the same bacterium was found earlier at the Kennedy Space Center, in 2007, before the launch of the Phoenix Mars Lander.

It´s believed that this bacterium may have survived the extreme procedures of cleaning and sterilization and the lack of nutrients. They discovered that the bacterium can survive in clean environments and with few or no nutrients, therefore, they concluded that the bacterium could survive in a trip to mars and be there already. They could also be living on meteorites since millions of years ago.

Do you Think we are Alone in the Universe?

The Great Filter

This theory tells about a gap that could exist at one period of time through the development of human evolution, from when man first appeared on the planet to present time. The evolutionary pathway of human evolution needs to go through a series of nine steps that if completed, sets humanity ready for the colonization of other worlds outside the solar system. But if one of this steps is incomplete, then, it means that humanity did not went through it in the past and still needs to complete this step in the future, but if all of the steps are complete by now, the next move would be space exploration and colonization.

On the other hand, if only one step needs to be completed, but humanity is unable to fulfill it in the future, then, man faces extinction and will never go beyond the limits of the solar system. This theory applies to all civilizations that could exist in the universe and if humanity has passed the great filter, we could become the first civilization going beyond our solar system.

Multiverses

The theory of fractals, patterns that repeat themselves infinitely, above, macroscopically, as well as below, microscopically, explains that there could exist an infinite number of universes.

Multiverses, meaning more than one universe have been thought of existing or deriving from our own universe, like bubbles in a hot pot of boiling water. With this vision of multiple and parallel universes existing side by side to the one we live in, is impossible to think that we´re alone in the universe. The only thing is that we cannot cross the borderline and enter another universe physically, but maybe we could by going through an astral projection while asleep.

Flat land and other Dimensions

This is a thought experiment in which a set of geometric figures with two dimensional forms, are easily seen and touched by a three dimensional figure living in a three dimensional world, like ours, but these two figures in 2D nor the ones in 3D can hear or sense the presence of another figure living in a fourth dimensional world.

A three dimensional being perceives height, width and length; for a two dimensional figure, comprehending a three dimensional world would be impossible. A three dimensional being, like ourselves, is not able to perceive the fourth dimension because our brain is used to perceive only things in three dimension. According to physicists, there exist at least 10 dimensions, but many of us will never be able to perceive them because we are accustomed to see life in three dimensions.

Extraterrestrial Intelligence

Throughout history, man has demonstrated that at one time or another, he would start a war against his own kind, killing each other, obeying his/her own basic nature of ; greediness, selfishness, enviousness, etc. Most of the times, we are unwillingly killing our own basic units of life (cells) when we engage in activities, including, exercise, indulgences of food, drugs, exposing ourselves to the sun´s rays over long periods of time, etc.

Encountering extraterrestrial life would not make us much better, instead, we will have another target with whom to discharge our basic human characteristics mentioned before. This is probably the reason why another intelligence, maybe more civilized than us, has not made contact with us, fearing encountering the uncivilized characteristics of humans, or maybe they could be expecting the right time, years still ahead, for the right time to sit at a table and talk intelligently with us.

We´re not Alone

We, as human beings, think that having two eyes, one brain, two feet, two hands, one brain, which sometimes does not function as good as it should, is synonym of superior intelligence: nevertheless, we´re surrounded by other living things, that although not similar to us, they possess characteristics, which could be superior to some of the ones we own.

Dolphins are marine animals known to have rescued sailor in danger, preventing people from being eaten by sharks. They´re sometimes used in treating people with disabilities, such as autism, for the benefits the contact with them provide.

Dogs , are animals which have been around people for more than 15000 years ago, when they first approach man camping around fires, and since then, they have been around people un their homes. Some have learned to behave docile in a home environment and there have been cases when a dog has saved the life of its owner. Other can be less docile and bite, but they behave according to how they are educated by people.

In conclusion, we are not completely alone in this world and the universe, we have been visited by bacteria coming from outside of this world and who knows what other living microscopic things coming from the outer limits of the solar system.

Your article does not consider other forms of life rather than C & H2O based forms. We can only detect life as we know it. It is much more likely that OTHER forms of life exist, out there. The massages attached to Voyager and other craft were very naïve. Why don't you agree that the Internet could become a life form that conserves its own survival (HAL like).

We know life that exists in the earth´s habitable zone and it depends on carbon and water; life existing beyond the habitable zone could exists and could depend on other elements, as well.

There are many theories about human evolution. This is just another one. It depends on which one we prefer to believe.

Which one you believe obviously affects your opinion about how likely life exists elsewhere in the universe. In my opinion it is extremely unlikely for C & H20 based life to exist elsewhere in the Universe, as we know it. We are alone! A small probability times a huge number of planets does not make it certain. Cheers
